Thirty-six years of contributions to queueing systems: a content analysis, topic modeling, and graph-based exploration of research published in the QUESTA journal

Abstract We investigate the 36-year history of research published in journal Queueing Systems: Theory and Applications (QUESTA), to uncover trends over time topics themes covered as well authorship, co-authorship, institutional affiliation. Our analysis includes three different approaches. First, we conduct a content titles abstracts using selected keywords examine models , methods concepts applied each article. Second, employ unsupervised topic modeling identify more hidden discussed journal. Finally, analyze co-authorship graph changes collaboration practices between authors their institutions. findings reveal persistent popularity studies focused on basic queues, queueing networks, systems. also confirm an increase among time.
